You are mistaken thinking you can sin and get away with it. Paul tells us that because we are under Grace doesn't mean we should sin more. If you sin after receiving the blood of Jesus, there is no more sacrifice to cover that sin.
One must be careful if you sit in a church that preaches grace everyday. What God is saying is if you have the love of God in your heart, then the rebellion to Him is over and He will cover your sin as you try to follow Him. If you treat His grace as a rag to wipe up your messes, you will suffer in this world.
An atheist would throw out there that I'm saying I can't eat lobster anymore, but you should know that is a dietary law, not The Law. Praying to a statue is still against the Law. Murder is against the Law.
The Old Testament is not a separate Book. Jesus came to fulfill the Old Testament. Jesus DID NOT come to start a new religion. If sodomy was against God's Law in the Old Testament, it's still against God's Law today, He never changes. If I were to commit adultery today, I can repent and God is quick to forgive, but God still frowns on adultery. It is a grave mistake to think you can sin and get away with it because we gave grace today.
If you notice, Abraham found grace in the Old Testament because He believed God. Noah was found to be a righteous man because he believed God. If you call sodomy good, do you believe God or not? If you think killing babies is a woman's right, do you believe babies are fearfully and wonderfully made by God while in the womb?
It's dangerous to try to twist your thinking to rationalize your sin into something God will accept because of Grace. We have grace because no one is perfect, but it is dangerous to justify your sin thinking grace will cover it. There is a huge heart difference. God id calling His people to sanctify themselves and to renew their minds. That doesn't include sinning and falling back thinking grace will cover you. If we are transforming our minds, what are we transforming it from? Don't agree with the world system thinking God will overlook it. These are the foolish virgins spoken of in Matt 25. They were not preparing for the wedding even though they agreed to get married. The Groom's solution was to send them where they could "buy and sell" in the world if they thought like the world. If you are led by the Holy Spirit, you will resemble the Old Testament saints more than this world.
I notice you said you didn't believe in some of the tenets of the Old Testament. No one is proposing killing sinners, but that doesn't make sin lawful. The heart condition says whether you get grace or not. If you treat the Blood of Jesus as a common thing, He doesn't have to cover your sin.
No, actually God said these people should be cut off, which is Bible Speak for killed. God demonstrated what He thought about it at Sodom and Gomorrah. He told us several times they would NOT see the Kingdom of Heaven.
Here’s what you posted....
The rest of your post has nothing to do with me. I said nothing about getting away with sin.
